Unable to import XML call costs and costs with more than 2 decimal digits

[davide.bonavita]

Hello everybody,
I'm trying to set up the call costs for our PBX, even if I can't understand if the value is referred to a minute of conversation or to a single second.

My first attempt has been to upload an XML, but once I upload it using the Import button, nothing happens. Here's are the first rows (it's very long):

<?xml version="1.0" encoding="utf-8"?>
<TenantProperties>
  <TenantProperty>
    <name>BILL_0000</name>
    <description></description>
    <type>String</type>
    <value n="default" p="default" r="1.0" />
  </TenantProperty>
    <TenantProperty>
        <name>Afghanistan Mobile AWCC </name>
        <type>String</type>
        <value n="Afghanistan Mobile AWCC " p="000009371" r="0.13508"/>
    </TenantProperty>
    <TenantProperty>
        <name>Afghanistan Mobile Etisalat </name>
        <type>String</type>
        <value n="Afghanistan Mobile Etisalat " p="000009373" r="0.09917"/>
    </TenantProperty>
    <TenantProperty>
        <name>Afghanistan Mobile Etisalat </name>
        <type>String</type>
        <value n="Afghanistan Mobile Etisalat " p="000009378" r="0.09917"/>
    </TenantProperty>

Then I've tried to create some costs manually, but if I write more than two decimal digits after the point I get this error:
